Solution :

The significant figure of a number are defined as the positional notation of that number which are most reliable and are absolutely necessary to represent the quantity of something.

In the context, we have to express the given numbers into three significant figures in the form of scientific notation or in the exponential form :

(i). 5590    -----    $5.59 \times 10^3$

(ii).  0.000498   -----    $4.98 \times 10^{-4}$

(iii) 135000  -----   $1.35 \times 10^5$

(iv) 0.000438   -----  $4.38 \times 10^{-4}$

The value of x in the expression<br> 2x/3 - 7 = 5 is
Andrej [43]

Answer:

The answer is X = 18

Step-by-step explanation:

2x/3 - 7 = 5

Multiply both sides if the equation by 3 : 2x - 21 = 15

Move the constant to the right hand side and change its sign : 2x = 15 + 21

Calculate 2x = 15 + 21

2x = 36

Divide both sides of the eqaution by 2 : 2x = 36

x = 18

Answer X = 18

1/5x-2/3y=30 when y=15
dolphi86 [110]

Answer:

Step-by-step explanation:

<u>Step 1:  Set y to 15 and solve</u>

<u />\frac{1}{5}x - \frac{2}{3}*15=30

\frac{1}{5}x-10=30

<em>Add 10 to both sides</em>

<em />\frac{1}{5}x-10+10=30+10

\frac{1}{5}x=40

<em>Multiply both sides by 5</em>

<em />\frac{1}{5}x*\frac{5}{1}=40*\frac{5}{1}

x=200

Answer:  x=200
